Abstract
An apparatus and a method is disclosed for providing a controlled separation of a structure that has been screened from the screening mask. A dampener pad floats with the mask as the screened structure is being separated from the mask. The mask is held in place by the dampener pad while the structure completely separates from the mask. The dampener pad assembly, then, in a controlled manner, brings the mask back to the original position, and the mask is then ready for the next screening operation.
Claims22
An apparatus for absorbing shock from a mask that is being separated from a structure, comprising, at least one means for absorbing shock, and at least one means for placing said shock absorbing means in contact with said mask prior to said structure being separated from said mask, wherein upon separation of said structure from said mask said shock absorbing means moving in synchronism with said mask and thereby preventing said mask from snapping back by absorbing the shock created when said structure separates from said mask.
The apparatus for absorbing shock from a mask that is being separated from a structure comprising at least one dampener pad cooperating with at least one dampening means, wherein upon the separation of said structure from said mask said dampener pad moves in synchronism with and prevents said mask from snapping back by absorbing the shock created when said structure separates from said mask.
A method for controlled separation of a mask from a structure comprising the steps of:
- (a) placing a mask having at least one opening over said structure,
- (b) applying a fluidic medium over said mask so that at least a portion of said fluidic medium passes through said opening in said mask and covers at least a portion of said structure, and
- (c) simultaneously separating said structure from said mask and applying a counter force over said mask so that said mask separates from said structure in a controlled manner.
